Electroencephalogram (EEG) is a non-invasive, high temporal-resolution technique for monitoring brain activity. However, affected by the volume conduction effect, EEG has a low spatial resolution and is difficult to locate brain neuronal activity precisely. The surface Laplacian (SL) technique obtains the Laplacian EEG (LEEG) by estimating the second-order spatial derivative of the scalp potential. LEEG can reflect the radial current activity under the scalp, with positive values indicating current flow from the brain to the scalp (“source”) and negative values indicating current flow from the scalp to the brain (“sink”). It attenuates signals from volume conduction, effectively improving the spatial resolution of EEG, and is expected to contribute to breakthroughs in neural engineering. This paper provides a systematic overview of the principles and development of SL technology. Currently, there are two implementation paths for SL technology: current source density algorithms (CSD) and concentric ring electrodes (CRE). CSD performs the Laplace transform of the EEG signals acquired by conventional disc electrodes to indirectly estimate the LEEG. It can be mainly classified into local methods, global methods, and realistic Laplacian methods. The global method is the most commonly used approach in CSD, which can achieve more accurate estimation compared with the local method, and it does not require additional imaging equipment compared with the realistic Laplacian method. CRE employs new concentric ring electrodes instead of the traditional disc electrodes, and measures the LEEG directly by differential acquisition of the multi-ring signals. Depending on the structure, it can be divided into bipolar CRE, quasi-bipolar CRE, tripolar CRE, and multi-pole CRE. The tripolar CRE is widely used due to its optimal detection performance. While ensuring the quality of signal acquisition, the complexity of its preamplifier is relatively acceptable. Here, this paper introduces the study of the SL technique in resting rhythms, visual-related potentials, movement-related potentials, and sensorimotor rhythms. These studies demonstrate that SL technology can improve signal quality and enhance signal characteristics, confirming its potential applications in neuroscientific research, disease diagnosis, visual pathway detection, and brain-computer interfaces. CSD is frequently utilized in applications such as neuroscientific research and disease detection, where high-precision estimation of LEEG is required. And CRE tends to be used in brain-computer interfaces, that have stringent requirements for real-time data processing. Finally, this paper summarizes the strengths and weaknesses of SL technology and envisages its future development. SL technology boasts advantages such as reference independence, high spatial resolution, high temporal resolution, enhanced source connectivity analysis, and noise suppression. However, it also has shortcomings that can be further improved. Theoretically, simulation experiments should be conducted to investigate the theoretical characteristics of SL technology. For CSD methods, the algorithm needs to be optimized to improve the precision of LEEG estimation, reduce dependence on the number of channels, and decrease computational complexity and time consumption. For CRE methods, the electrodes need to be designed with appropriate structures and sizes, and the low-noise, high common-mode rejection ratio preamplifier should be developed. We hope that this paper can promote the in-depth research and wide application of SL technology.

ObjectiveExisting artificial vision devices can be divided into two types: implanted devices and extracorporeal devices, both of which have some disadvantages. The former requires surgical implantation, which may lead to irreversible trauma, while the latter has some defects such as relatively simple instructions, limited application scenarios and relying too much on the judgment of artificial intelligence (AI) to provide enough security. Here we propose a system that has voice interaction and can convert surrounding environment information into tactile commands on head and neck. Compared with existing extracorporeal devices, our device can provide a larger capacity of information and has advantages such as lower cost, lower risk, suitable for a variety of life and work scenarios. MethodsWith the latest remote wireless communication and chip technologies, microelectronic devices, cameras and sensors worn by the user, as well as the huge database and computing power in the cloud, the backend staff can get a full insight into the scenario, environmental parameters and status of the user remotely (for example, across the city) in real time. In the meanwhile, by comparing the cloud database and in-memory database and with the help of AI-assisted recognition and manual analysis, they can quickly develop the most reasonable action plan and send instructions to the user. In addition, the backend staff can provide humanistic care and emotional sustenance through voice dialogs. ResultsThis study originally proposes the concept of “remote virtual companion” and demonstrates the related hardware and software as well as test results. The system can not only achieve basic guide functions, for example, helping a person with visual impairment to shop in supermarkets, find seats at cafes, walk on the streets, construct complex puzzles, and play cards, but also can meet the demand for fast-paced daily tasks such as cycling. ConclusionExperimental results show that this “remote virtual companion” is applicable for various scenarios and demands. It can help blind people with their travels, shopping and entertainment, or accompany the elderlies with their trips, wilderness explorations, and travels.

Objective To systematically evaluate the short-term efficacy and safety of lung subsegmentectomy and segmentectomy in the treatment of small pulmonary nodules. Methods Computer searches were conducted on PubMed, The Cochrane Library, EMbase, Scopus, Web of Science, SinoMed, Wanfang Data, VIP, and CNKI databases to collect relevant literature on the short-term efficacy and safety of lung subsegmentectomy and segmentectomy for small pulmonary nodules from the inception to April 2024. Two researchers independently screened the literature and extracted data according to inclusion and exclusion criteria. Meta-analysis was performed using RevMan 5.4 software, and the Newcastle-Ottawa Scale (NOS) was used to assess the quality of the selected literature. Results A total of 15 retrospective cohort studies with 2417 patients were included, among whom 796 patients underwent lung subsegmentectomy and 1621patients underwent segmentectomy. The NOS scores of the included literature were all≥6 points. Meta-analysis results showed that compared with segmentectomy, lung subsegmentectomy had a lower overall postoperative complication rate [OR=0.54, 95%CI (0.39, 0.75), P<0.01] and fewer lymph nodes dissected [MD=−0.43, 95%CI (−0.81, −0.06), P=0.02]. There was no statistical difference between the two surgical methods in terms of operation time [MD=5.11, 95%CI (−4.02, 14.23), P=0.27], intraoperative blood loss [MD=−14.62, 95%CI (−29.58, 0.34), P=0.06], postoperative hospital stay [MD=−0.24, 95%CI (−0.49, 0.01), P=0.06], postoperative drainage time [MD=−0.14, 95%CI (−0.46, 0.18), P=0.40], intraoperative margin width [MD=0.10, 95%CI (−0.16, 0.35), P=0.46], or recurrence rate [OR=1.57, 95%CI (0.53, 4.61), P=0.42]. Subgroup analysis results showed that when using uniportal video-assisted thoracoscopy for surgery, compared with segmentectomy, lung subsegmentectomy had less intraoperative blood loss [MD=−15.57, 95%CI (−28.84, −2.30), P=0.02], shorter postoperative hospital stay [MD=−0.49, 95%CI (−0.63, −0.35), P<0.01], shorter postoperative drainage time [MD=−0.19, 95%CI (−0.35, −0.03), P=0.02], and lower overall complication rate [OR=0.55, 95%CI (0.31, 0.98), P=0.04]. Conclusion Lung subsegmentectomy can achieve similar efficacy as segmentectomy and has a lower overall postoperative complication rate. In terms of safety, lung subsegmentectomy can achieve a margin range close to that of segmentectomy. When performing uniportal thoracoscopic surgery, lung subsegmentectomy has advantages over segmentectomy in terms of intraoperative blood loss, postoperative hospital stay, and drainage time.

The paper is to establish an UPLC-MS/MS method for the simultaneous determination of 19 components in Microctis Folium from different production areas. The 50% methanol was used as extraction solvent. The Agilent ZORBAX SB C18 (150 mm × 2.1 mm, 1.8 μm) column was used; mobile phase was acetonitrile - 0.1% acetic acid with gradient elution, flow rate was 0.3 mL·min-1, colume temperature was 30 ℃, and the injection volume was 2 μL; electrospray ionizaton source was used and detected in negative ion mode. The results showed that the established UPLC-MS/MS method could well separate the 19 components, and the methodological investigation results of 19 components were good. By means of orthogonal partial least squares discriminant analysis (OPLS-DA), 28 batches of Microctis Folium samples from different production areas can be divided into three categories, Guangdong, Guangxi and Hainan are each classified into one category, and 10 signature compounds which affecting the quality differences of different production areas were screened out. The established method is accurate, reliable, sensitive and reproducible. It can provide a basis for the establishment of the quality standard of Microctis Folium, as well as for safety and quality research.
